We monitor subjects' eye, head, and hand movements while they perform a block-copying task. In this photo, I am wearing the headband mounted ASL eyetracker which monitors eye-in-head position using an infrared illuminator and a small video camera visible at the front of the headband. The eye's image is reflected by the visor (which reflects IR while passing visible light). Movements of the head and hand are monitored by magnetic coils on the headband and hand, respectively. The video monitor in the background shows the image captured by the 'scene camera' mounted on the headband (visible on the near side of the headband) The crosshair cursor on the monitor indicates where in the scene the subject is looking (in this case, I am fixating the area on the board where I am placing a block).
